What is the main role of the Jakarta EE platform in enterprise application development?

The Jakarta EE platform (formerly Java EE) provides a standardized set of specifications and APIs for developing scalable, reliable, and portable enterprise applications in Java. The main role of Jakarta EE is to simplify the creation of server-side applications by providing:

• Lifecycle management of components (EJB, servlets)
• Built-in support for transactions and security
• Mechanisms for interaction between components (JPA, JMS, CDI)
• Standardized web services and REST APIs

Thus, Jakarta EE allows developers to focus on business logic, using ready-made infrastructure solutions for scalability, reliability, and integration in an enterprise environment.
